Your Role

We are evolving from traditional analytics to advanced AI engineering and are looking for a strong software engineer to help build and scale production-ready AI systems across the Group. Our AI platform is built around a central Knowledge Graph and already powers chat, voice, and smart routing capabilities across multiple European markets. You will play a key role in taking these systems from prototypes to scalable, user-facing applications.This role is ideal for a hands-on builder who enjoys working across the stack – from backend APIs and data pipelines to intuitive front-end interfaces.

Your Responsibilities

• Build and scale AI-backed applications using Python and FastAPI


• Optimize GraphRAG pipelines for high-quality retrieval and context generation


• Develop and maintain APIs, data pipelines, and graph-based systems


• Turn prototypes into robust, production-ready solutions


• Work on core AI infrastructure (routing, data quality, monitoring, deployment)


• Collaborate on chat, voice, and intelligent routing solutions

Your Profile

• Strong software engineering background with focus on backend development


• Excellent Python skills and experience with API development (e.g. FastAPI)


• Experience or strong interest in AI systems (RAG, LLMs, knowledge graphs)


• Familiarity with graph technologies (e.g. Neo4j, NetworkX) is a plus


• Basic frontend experience (React) or willingness to learn


• Understanding of CI/CD and modern development workflows


• Pragmatic, product-oriented mindset and willingness to work on end-to-end solutions


• Tech Stack (excerpt) - Python (FastAPI) on k8s, Azure OpenAI, Neo4j, React, Snowflake, Airflow, GitHub, Jenkins

Why Join Us

• Work on cutting-edge AI systems in production (not just prototypes)


• High impact across an international banking group


• Strong engineering focus at the intersection of software, data, and AI
